SPECIFICATION forming part of Letters Patent No. 225,185, dated March 2., 1880. i Application fileu July as, 1879.

A swiftfor winding silk and other kinds of thread in which the spindles may be easily changed when desired.

It is well understood by those who arefamiliar with the working of swifts as now constructed, with a solid hub, that great difficulty has been experienced in changing the spindles, which is frequently done, and that it is very difficult to remove broken spindles to replace -them by others, which difculty is overcome by my invention.

The invention consists in a swift composed of a body having a 'weight-rin g turned thereon, the object of which is to support a weight in order to regulate the tension of the thread by preventing the swift from unwinding the thread faster than is required by the receiving-spool. On the body of the swift there are hubs formed at each end, and these hubs are made in sections, which separate at the point where the spindles are inserted. The separate parts of the hubs are held together by a bolt and jam-nuts.

' serted spindles, and near the tops of .these is a side view of half of one of the hubs. Fig. 3 is a front view of one of the hubs with the parts separated, showing the bolt and the sockcts where the spindles are inserted, and

In the hubs there are inalso the weight-ring. Fig. 4 is an end view, showing the thread on the swift.

AI indicates the body of the swift. A indicates the weight-ring, as seen in Figs. 1 and 3. B indicates the sectional hubs. c o indicate the spindles, which are inserted in the grooves 02, made in each half of the hubs. c' indicates the cords which support the hanks of thread, as seen in Fig. 1. 'd indicates the bolt. dicates thejam-nuts, as seen in Figs. 1,3, and 4.

The operation of my swift is as follows: The hanks of thread to be unwound are placed on the cord c', as shown in Fig. 4:, the swift is put in position, generally in front of a winding-frame, and the end of the thread is taken to a receiving-spool, which is in motion. This receiving-spool draws the thread and rotates the swift during the unwinding operation. When the hank of thread is unwound the swift is taken away or supplied with additional thread. The weight-ring, being suitably weighted when required, prevents the swift from turning faster than required by the receiving-spool and keeps a proper tension on the thread.

When the spindles c are to be changed, or when a spindle has been broken and is to be replaced by a new one, the jam-nuts e on the bolt d are simply unscrewed and the parts or sections of the hubs B separated, and the change made. This is easily effected. Then the parts or sections are again drawn and kept together by screwing up the jam-nuts c on the bolt d.

Much inconvenience and loss of time, as well as much expense, are saved by the use of my improved swift. e

What I claim as new, and desire to obtain by Letters Patent, is-- ein-' A swift composed of the body A', weightring A, sectional hubs B, spindles c, cords c', bolt d, and jam-nuts c, said sectional hubs being held together by said bolt and jam-nuts, lsubstantially as and for the purpose set forth.
